If the car is parked in the same place for 2 months, there will be no problem in general. Attention should be paid to the battery capacity. Kind of like our cell phones. If the power is turned off for 1 or 2 months, the power will be less.
If the parking environment is not good, the probability of problems will increase.
Under normal circumstances, there is basically no big problem.
First of all, many friends will care: will the car rust if it is parked for a long time?
Generally speaking, manufacturers will set an anti-corrosion standard, and these experimental procedures are much stricter than normal shutdown for 2 months.
Song Hailin, Xing Na and others published a paper "Interpretation and Thinking of General Motors Anti-corrosion Standard System" in the magazine "Corrosion and Protection", which said.
Volkswagen's anti-corrosion test standard, PV1210-20 16, a test cycle will be divided into three stages: salt spray for 4 hours, storage in standard climate for 4 hours, and condensation16 hours.
After every 5 cycles, add 48 hours of constant temperature and humidity storage. According to the anticorrosion requirements of different parts, 15 to 90 cycles should be carried out.
In other words: the car can reach this standard, generally speaking, it will not rust after stopping for 2 months.
Of course, some friends are worried about the other part: whether the oil in the car will expire. This depends on the shelf life. Let's talk about whether the fuel will expire first.
China Petroleum issued a document in 2020: the shelf life of ethanol gasoline is basically around 1 month, that of ordinary gasoline is 3 months under normal circumstances, and that of diesel oil is at least 12 months at 20℃.
That is to say: if you add ethanol gasoline and stop using it for 2 months, it is best to test it first. If you report a faulty light, you should go to the repair shop as soon as possible to see if you can take it out.
Gasoline and diesel are basically not a big problem. As for the oil in the engine, don't worry too much.
Wei Lei of the General Institute of Mechanical Science has a doctoral thesis "Research on Service Life Evaluation Technology of Automobile Engine Lubricating Oil", which reads.
He did a static test of the oil. He used three kinds of metal containers: cast iron, copper alloy and aluminum alloy to conduct two groups of static tests for six months each.
The test shows that the physical and chemical properties and composition of lubricating oil have little change under the static state or a small amount of operation for 6 months.
Nothing for six months, don't worry for two months. But one thing you should pay attention to is that the day you stopped was not the day you just changed the oil.
But batteries need special attention.
Although two months is really not a big problem and the car is not that expensive, the battery really depends. Stop for 2 months at once, the battery loss probability is not small, and the car will not start.
The battery is like this. If you stop here and do nothing, there will still be a loss of motivation. The loss mainly comes from two aspects.
No.65438 +0, even if the car stops, some sensors like ECU and anti-theft system will work there even if the clock is good, which will generate electrostatic current.
It's like: we fell asleep and our metabolism stopped without saying anything. "Hey," I slept really well yesterday. No heartbeat for two hours. There is no such person, is there?
Yu and Wu Zhenyun published a paper "Analysis of Calculation Method of Static Current Parameters of Automobile" in the magazine of Automotive Practical Technology.
It says: At present, the static current parameters of mainstream vehicles on the market are between 10 ~ 30mA, and some models can be reduced to below 10mA.
What concept? Suppose a car is a 12V, 60Ah battery, and the battery will be marked there.
It means that 1 hour can be continuously output at a current of 60A. If the current is 30mA, it can output continuously for 2000 hours, about 83 days.
Eh, isn't 83 days more than two months? The problem is not big.
We should also consider the second kind of loss, that is, the self-discharge of automobile batteries.
Nie, Zhao and others published a paper "Analysis and Prevention of Auto Lead-acid Battery Self-discharge" in Automotive Engineer magazine.
As mentioned above, in the case of normal self-discharge of the battery, the power loss in one day and night will generally not exceed 0.7%. ?
The actual power to ensure the normal start of the vehicle should not be less than 65% of the rated power.
The previous 0.7% was not much, but the cumulative 60 days is actually quite a lot. If you have friends who are good at math, you can calculate: 0.993 is 6 1 power, which is almost 0.65 1.
Therefore, when the static current and self-discharge loss are added together, it is really possible that it will not last for 2 months.
If the battery itself is used for a long time, the self-discharge will be serious in some years, and it may be too low to start for more than ten days.
Therefore, the parking time is really long, and there is no way to open it once a week, so friends who come back from the charging point can consider disconnecting the negative electrode of the battery to avoid not being able to start it directly in the future.
If the conditions are better, buy a charger to charge it regularly, just as we used to do in 4S shop.
If the parking environment is not good, there will be additional problems
In addition, if the parking environment is not very good, there may be some additional problems after parking for 2 months.
For example, if you park your car on the roadside or under a tree, the most direct things are chewing gum and bird droppings. If you don't wash your car for a long time, the paint will become potholed and you won't be able to get it back.
If the tree is blown down by the strong wind and the car is crushed in bad weather, the loss is not clear, right?
Although the probability is really small, these news videos are really available online, and sometimes insurance does not necessarily pay.
Is it okay to park in the basement?
In fact, if the ventilation inside the underground garage is not very smooth and the environment is a little humid, the car may be moldy, which is also quite troublesome.
Sunrain Dang of Southeast University has a master's thesis "Study on the Risk of Mold Growth in Air Infiltration of Building Walls", which says so.
There is a strong correlation between mold growth and humidity. With the increase of relative humidity, the growth rate of microorganisms will obviously accelerate. When the relative humidity exceeds 80%, mold will multiply in large numbers.
Let's just say that at the same temperature, the wetter the basement, the easier it is for the car to get moldy.
If you want to avoid mildew, the simpler way is to throw some desiccant and drying bag in the car, and it won't cost a few dollars. You can buy it online, but I don't sell it at home.
If the car that has been parked for a long time is really moldy, it is not good to drive directly. You should pay attention to this.
Qianjiang evening news reported a case in June, 20021year: Mr. Liu's car in Hunan was parked at his home for two months, and the car got a little moldy as a result. He didn't pay much attention to it, but he didn't clean it up in time while driving.
As a result, I was infected with Legionella and stayed in the intensive care unit for half a month. You might as well listen to it.
The parking environment is relatively good, and it is no problem to stop for 2 months.
So in general, if the parking environment is good, it will not be too much problem to stop for 2 months, as long as the battery is not dead.
If the parking environment is poor, these serious problems are only those cases. You should also pay attention to them. It is necessary to watch videos online first, which is really possible.
Is it necessary for cars to catch fire every 6 or 7 days 1 time?
Having said so much just now, many friends have some regrets. It is not good to stop like this for a long time.
